It has silver-toned steel broad arrow hands with luminous inserts, a steel center sweep second hand, and there is a luminous minute/second scale around the perimeter. It's a Certified Master Chronometer, approved by METAS, and it's resistant to magnetic fields up to 15,000 gauss. It has a 55-hour power reserve at full wind, and it's water resistant to 60 meters/200 feet. The 12.8mm thick case, dial, and movement are all signed.

This Omega Railmaster 1957 Trilogy 220.10.38.20.01.002 has a mechanical automatic self-winding Omega caliber 8806 movement.

The Omega Railmaster 1957 Trilogy 220.10.38.20.01.002 was introduced in 2017 in a limited edition to 3557 examples. It's a 60th Anniversary tribute to one of three classic timepieces released in 1957. This Railmaster is based on the original antimagnetic watch engineered for people who worked in close proximity to electrical fields in the fifties. It captures the 1957 model's simple style, but it's powered by the new Master Chronometer 8806 engine that resists magnetic fields of up to 15,000 gauss.
